“…This is because the 4d electrons are somewhat more localized than the 5d electrons. 42) As listed in Table 3 12 shows no long-range magnetic ordering down to 0.5 K, the magnetic anomaly observed at 2.4 K in Ba 4 PrRu 3 O 12 is due to the magnetic interactions of the magnetic moment of Pr 4+ ions. The results of the specific heat measurements and evaluation of the magnetic entropy change due to the antiferromagnetic ordering have quantitatively cleared this point.…”

“…Such highly oxidized cations from the second or third transition series sometimes show quite unusual magnetic behavior. Any of the double perovskites Ba 2 LnRuO 6 (Ln = La ~ Lu) [2,4,5,[9][10][11][12] and Sr 2 LnRuO 6 (Eu ~ Lu) [3,4,[6][7][8][12][13][14] show an antiferromagnetic transition at low temperatures, and the transition temperature is higher than that for the compounds in which the magnetic ion at the B site is Ru 5+ ion only. Among them, the transition temperature for Ba 2 PrRuO 6 is astonishingly as high as 117 K [10], and Ba 2 NdRuO 6 transforms to the antiferromagnetic state at 57 K [9].…”

“…Not the A site ions but the B site ions normally determine the physical properties of the perovskites [1] The solid-state chemistry of such mixed-metal oxides containing platinum group metals has attracted a great deal of interest. The preparation, crystal structures and magnetic properties of double perovskite oxides containing Ru ion, A 2 LnRuO 6 (A = alkali-earth metals), where Ln represents a rare earth ion, have been studied [2][3][4][5][6][7][8][9][10][11][12][13][14]. The electronic configuration of Ru 5+ is…”

“…The perovskite structure can be described as a framework of corner-shared BO 6 octahedra, which contain A cations at 12-coordinate sites. The preparation, crystal structures and magnetic properties of double perovskite oxides containing Ru ion, A 2 LnRuO 6 (A = alkali-earth metals), where Ln represents a rare earth ion, have been studied [2][3][4][5][6][7][8][9][10][11][12][13][14].…”

“…Double perovskite compounds SrCaLnRuO 6 (Ln = La, Pr, Nd) were prepared as a single phase. X-ray diffraction measurements show that Ca 2+ and Ln 3+ ions are partially disordered at the A site and half of the B site of the perovskite ABO 3 , and that Ca 2+ /Ln 3+ and Ru 5+ ions are regularly ordered at the B site.…”
